Book mark this: https://www.safaribooksonline.com/library/view/regular-expressions-cookbook/9780596802837/ch06s09.html[^]
The above is for finding All-Cap Roman Numerals. Check against this, if fail, then have another similar regex check for small cap, just convert all the letters in the previous regex to small ones. Or

(ALL-CAP regex)|(small cap regex)

Solution 1

You can try this expression

(?<roman>\b[IVXLCDM]+\b)|(?<roman>\b[ivxlcdm]+\b)

It basically says, either small letters OR (|) capital letters, but not both.
Make sure you turn off IgnoreCase.
